Keeping track of device interactions in smart environments is a challenging
task for everyday users. Given the expected high number of communicating
devices in future smart homes, it will become increasingly important to put
users more in control of their smart environments by providing tools to
monitor and control the interactions between smart objects and remote
services.
We present a system for collecting and visualizing interactions of
Web-enabled smart things and Web services in an intuitive and visually
appealing way. Our tool displays device interactions both using a Web-based
visualization application and in the form of a "magic lens" by augmenting
the camera view of a tablet with relevant connections between recognized
devices in the camera's field of view.
